Two problems related to extraction of files exist in gzip:

The first problem is that gzip does not properly sanitize filenames
containing / when uncompressing files using the -N command line
option.

The second problem is that gzip does not set permissions on newly
extracted files until after the file has been created and the file
descriptor has been closed.");
